foall whomz't mag/concern:

Be it known that ll,`W1i.LIAr/r G. Cox, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and 5 State of hio, have invented certain new and useful improvements in -a Sectionaly Bumper forMotor Vehicles, ofA which the following is a specification.

My invention relates to an improvement to in a sectional bumper for motorfvehicles, the

object being to provide'a wide-faced bumper of symmetrical form and attractive appearance in' which'l separate U members form end impact portions and a plural numberof spring lbars form the -middleimpact portion of the bumper, and in which a single bar or a pair of independent attachment arms are used to support the U members and the'main impact bars jointly but separably upon v'the vehicle frame. rl`his sectional construction permits this bumper to be easily assembled and'disassembled; and it is also convenient to repair or replace any section or part when bent or damaged by accident or collision.

. In the -annexed drawings, Fig. 1 is a top view of one form of my improved bumper attached tofa. motor-vehicle which is shown in dotted lines. Fig. 2 is a front View of the same bumper. Fig. 3 is a-ront view of the rear supporting' bar. Fig. 4 is a front View .Y

of the bumper without the middle impact bars.r Fig. l5 is a perspective view of one of the main impactfbars. Fig. 6 is a vertical -section of the bumper on line 6--6 of Fig. 1, 85 showing the vertical frame and a bumper supporting bracket in dotted lines. Fig. 7'

is a plan View corresponding to Fig. l but showing the two separate supporting arms instead of the single supporting bar. Fig. 8 is a front view of\one of the supporting arms, and Fig. 9A a front view o'if'one of the U-shaped impact members. Fig. 10 is a top View of a bumper embodying the same U members but showing aV di`er- 35 'ent form-l of attachment arm and crossed impact bars. the bumper delineated in Fig. 10. Fig. l2 is a plan View of a bumper having the same detachable U sections at its opposite ends but a slightly different form of attachment Fig. 11 is a front view. oi"A arm, andA Fig. 13 is a front View of one of these attachment armsf i Referring to Sheet 1 of the drawings,the bumper shown thereon consists of a front impact portion in the form'of a narrow '55 elongated loop having round closed ends. The parallel impact portions of this loop are flat and lie in higher and lower planes to provide a wide-faced bumper as compared with a single bar bumper. The loop is made in four pieces,l the ends consisting of two similar U members 2-2 made of Hat spring bars bent double edgewise to provide straight parallellegsB-pf equal length, and the middle portion of the bumper comlprising/mvo straight spring bars 4-4 of I equal length. The leg-"portions of the two U members 2 2 and the ends ofthe two bars 4.-1 are provided with bolt openings to re'- ceive bolts 5 in uniting the parts together when overlapped;v Thefsame bolts extend through bolt openings 6 formed in the vertically-bent extremities 7 7 of a supporting'member 8 and detachably unite all these parts together. Member 8 may be a single '75 flat bar having its opposite ends curved and rounded and bent inwardly for a short distance to provide spring loops 9 9. Each extremity 7 of bar 8v is bent downwardl;7 and thence-upwardly to provide a relatively 8@ wide face vertically against which the two legs 8-3' of il member 2 may be rigidlyclamped, substantially as shown in Figs. l' and 4.' Theft'wo mainimpaot bars llil are clamped horizontally one aboveV the other against the outer Fiat faces of 3--3 and form prolongations of'thelegs'c-f both U members which extend in opposite direc-- tions and are also preferably cui".y wardly in the fiat portions at or near ih round portions.

n Where a single rear bar is used as shown in Fig. l, it may be gripped and held in suitable clamping device or `attachntueat bracket v'affixed to or forming part ofthe vehicle frame. The same mode of mounting the bumper upon the-vehicle maybe practiced where the middle portion of rear bar 8 is omitted and the same loop end portions 9-9 are retained. as shown in Fig. 7. Thus END ell

instead of a single rear bar I may use two separate rear aiins 8-8 to attach the front impact members to the vehicle. The front extremity 7 of each arm 8 is also bent downwardly and upwardly in the same way as bar 8 to provide a wide vertical face capable of permitting two main impact bars 4 to be clamped at different elevations thereto.

In Fig. l() I show separate attachment arms 1Q having the same vertically-extended extremities 7 as in bar 8 and arms 8 and the same loop formation 9, but the rear portions of arms 12 are curved and extend rearwardly on straight lines to permit them to be bolted or clamped to the sides of the vehicle frame instead of to front projecting brackets. The two main impact bars JJ-4 vare also shown horizontally crossed instead of parallel, which makes the bumper wider at its ends than at its middle but these middle barsare still prolongations of the legs of the U members at the ends of the bumper.

In Figs. 12 and 13, I show a further modification of a. bumper attachment arm Il which possesses no loop portion 9 but is instead curved rearwardly from the verticallyi bent extremity 7 to a straight attachment end In Fig. 13 this extremity 7 is the sanic :.1:` in the other forms herein described but shown. inverted.

The opposite ends of my broad-faced bumper', in all the forms described, are U- shaped and made detachable from the middle impact bars and the attachment arms. The separate parts can be packed compactly for shipment. the shock or impact may occur directly at thc middle or either end. If severe the bumper becomes bent orI damaged where the buniper: is struck and the shock is absorbed. in the present bumper if either end is daniaged, it can be readily detached and repaired. Ihe same is true of the main bars at. the middlel and of the supporting arms also. it is also a simple matter to straighten any oneof the several parts of the bumper when bent, because these may be detached for that purpose. This is of advantage when traveling, especially if the ends alone are bent back against a wheel. `In fact either end may be removed temporarily, if damaged, and the remainder of the bumper mayl be fastened together and still have utility. l

What I claim is: g

l. 'A sectional bumper for motor-vehicles, comprising flat end members of relatively elongated U shape, flat connecting bars uniting the legs of said U members together, and a bar having vertically-extending extremities adapted to Support said members and ba s to present duplicate impact facesfabove and below the longitudinal median line In the event of a collision,

2. A sectional bumper for motor-vehicles, comprising a pair of U members, a pair of fiat spring bars, supporting means at the' 'rear side o said members and bars having ping the ends of thelegs of said U members,

and a single bar having looped ends and vertically-extending extremities adapted to support said U members and bars in the relation specified. i'

Li. A sectional bumper for motor-vehicles, comprising a pair of end members each made of flat steel bars doubled edgevvise into a relatively long and narrow U shape, a single support for both legs of each member, a pair of flat steel bars extending between said U members as prolongations of the legs thereof, and devices adapted to fasten said bars and members detachably together upon said supporting means.v

5. A sectional bumper for motor-vehicles,
